MATLAB: How to concatenate a row vertically every 5 cells

Question

Hi all,

if A is an array 1 x 100, how can I turn it into an array of 10×10 or 20 x 5?

Thanks

You can use reshape command to do that.

A=randi(20,1,100);
reshape(A,20,5);
reshape(A,20,5);

It reshapes along the column of the matrix. This below example clarifies your concept:

A = 1:10;
B = reshape(A,[5,2])
B =
     1     6
     2     7
     3     8
     4     9
     5    10
